TECHNICAL HELD

Embodiments are generally related to all terrain vehicles. Embodiments are also related to vehicle drive transmission systems. Embodiments are additionally related to a multidirectional vehicle chassis assembly.

BACKGROUND OF THE INVENTION

All-terrain vehicles (ATV's) such as, for example, haulage vehicle, high-mobility wheeled vehicle for transporting long loads over a road less terrain, a tractor, a rough terrain vehicle, a reconfigurable mobile vehicle, and an articulated tracked vehicle include a chassis assembly with a transmission system that works activating each of the vehicles mechanisms and gears with an electric motor. A body of the vehicle is typically supported on the chassis assembly which includes a frame, wheels, and an engine system. Majority of prior art chassis assemblies do not drive its force multi directionally and do not provide ample mobility and grip as required on a hard to reach terrain.
Based on the foregoing, it is believed that a need exists for an improved central multidirectional drive transmission system. A need also exits for an improved chassis assembly, as described in greater detail herein.

BRIEF SUMMARY

The following summary is provided to facilitate an understanding of some of the innovative features unique to the disclosed embodiment and is not intended to be a full description. A full appreciation of the various aspects of the embodiments disclosed herein can be gained by taking the entire specification, claims, drawings, and abstract as a whole.
It is, therefore, one aspect of the disclosed embodiments to provide for an improved central multidirectional drive transmission system that activates each mechanisms with an electric motor and/or a hydraulic injection motor.
It is another aspect of the disclosed embodiments to provide for an improved chassis assembly in order to drive force multi directionally with semi mechanisms that permits the vehicle's ample mobility and grip as required on a hard to reach terrain.
The aforementioned aspects and other objectives and advantages can now be achieved as described herein. A central multidirectional transmission system is disclosed which includes a chassis having a central base and a central multidirectional mechanism, a rear suspension assembly, and a front suspension assembly. The rear suspension assembly, the front suspension assembly, and one or more mechanical and structural components (e.g., engine, transmission, passenger seats, etc.) are mounted to the central base. The rear suspension assembly serves as a base for a rear suspension and a telescoping mechanism and is attached in a pivotal manner to the central base. The front suspension assembly is also mounted to the central base in a manner which permits the front suspension assembly to rotate at varying vertical and horizontal angles with respect to a longitudinal axis of the vehicle.
The front suspension assembly further includes an upper forward suspension bar, a lower forward suspension bar, and a torsional shaft which joins a front support with a front differential base. The front suspension assembly is attached to the center base via a four-arm system which are linked pivotally to the center base on one end and to the front support on the other end in order to permit a vertical displacement of the front suspension assembly with respect to the center base. The displacement may be commanded and controlled via an actuator system such as, for example, a servo motor, a hydraulic actuator, or a pneumatic actuator.
The front suspension assembly further includes a torsional shalt that is fixed to a front differential base and mounted to the front support with bearings to permit the assembly to rotate with respect to the longitudinal axis of the chassis. An axle runs through the center of the shaft and transmits the torque from the transmission to the front differential. The front differential base is held level with respect to the horizontal axis via the torsional shaft that is fixedly coupled with a gear. The gear is engaged by another gear, which is in turn fixedly coupled to a disc and held or released by a brake mounted to support. The brake is normally on so as to maintain the front suspension assembly level with the center base. The brake may be disengaged to permit the front suspension assembly to tilt clockwise or counterclockwise so that a free spinning tire can make contact with the ground and other solid object in order to achieve traction.
The rear suspension assembly includes a rear suspension mechanism mounted to the center base to permit the whole rear suspension assembly to rotate up and down with respect to the center base. The rear suspension mechanism includes a telescoping bar fixed to a rear differential base and may slip in and out of the rear suspension mechanism, effectively elongating the rear suspension assembly by a protrusion amount. The rear suspension mechanism is rotated downward to create a positive ventral space for additional ground clearance. The rear suspension mechanism may also be rotated upward if and when a negative ventral space is required. Additionally, the front suspension assembly may be raised or lowered independently or in conjunction with the rear suspension assembly to achieve any number of configurations as required to overcome an obstacle and to navigate a specific terrain.
The rear suspension mechanism further includes a shaft and a plate that fit inside a hollow cylinder and is free to rotate axially. A gear spins freely with respect to the shaft and is engaged by a worm mounted to the hollow cylinder. A torsion spring also fits inside the hollow cylinder and is attached to the plate at one end and to the gear at the other end. The worm is turned via an electric motor, hand crank, or any other suitable means which causes the gear to turn around the shaft. As one end of a torsion spring is held to the gear, turning the gear causes the coils of the spring to tighten or unwrap based on the direction of turn. Such an approach causes the rear suspension mechanism to rotate upward or downward (based on whether the tension in the spring is being increased or decreased) and maintains a level of torsional resistance (which in effect can constitute a secondary suspension mechanism).

DETAILED DESCRIPTION

The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate at least one embodiment and are not intended to limit the scope thereof.
The embodiments now will be described more fully hereinafter with reference to the accompanying drawings, in which illustrative embodiments of the invention are shown. The embodiments disclosed herein can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
FIG. 1 illustrates a side view of a central multidirectional transmission system 50 and a chassis 52 of a vehicle, in accordance with the disclosed embodiments. The chassis 52 includes a central base 10, a rear suspension assembly 42, and a front suspension assembly 16. The rear suspension assembly 42, the front suspension assembly 16, and one or more mechanical and structural components (e.g., engine, transmission, passenger seats, etc.) can be mounted to the central base 10. The rear suspension assembly 42 serves as a base for a rear suspension and a telescoping mechanism, and the rear suspension assembly 42 is attached in a pivotal fashion to the central base 10. The front suspension assembly 16 is also mounted to the central base 10 in a manner which permits the front suspension assembly 16 to rotate at differing vertical and horizontal angles with respect to the longitudinal axis of the vehicle.
FIG. 2 illustrates a top view of the central multidirectional transmission system 50 and the chassis 52, in accordance with the disclosed embodiments. The front suspension assembly 16 further includes an upper forward suspension bar 12, a lower forward suspension bar 36, and a torsional shaft 24 which joins a front support 20 with a front differential base 26. The front suspension assembly 16 is attached to the center base 10 via a four-arm system (not shown). The four-arm system is linked pivotally to the center base 10 on one end and to the front support 20 on the other end in order to permit a vertical displacement of the front suspension assembly 16 with respect to the center base 10. The displacement may be commanded and controlled via any suitable actuator system such as, for example, a servo motor, a hydraulic actuator, or a pneumatic actuator.
The torsional shaft 24 is fixed to the front differential base 26 and mounted to the front support 20 with bearings or any other means to permit the front suspension assembly 16 to rotate with respect to the longitudinal axis of the chassis 52. An axle 30 runs through the center of the shaft 24 which transmits the torque from the transmission to a front differential 28. The rear suspension assembly 42 includes a rear suspension mechanism 32, a rear differential base 92, and a rear differential 80. The rear suspension mechanism 32 is mounted to the center base 10 such as to permit the whole rear suspension assembly 42 to rotate up and down with respect to the center base 10.
FIGS. 3-4 illustrate a cut-away view of the front suspension assembly 16 that controls degree of tilt with respect to a longitudinal axis of the vehicle, in accordance with the disclosed embodiments. The front differential base 26 is held level with respect to the horizontal via a disc-brake system. The torsional shaft 24 is fixedly coupled with a gear 62. The gear 62 is engaged by another gear 68, which is in turn fixedly coupled to a disc 72 which is either held or released by a brake 70 mounted to the support 20. The brake 70 is normally on so as to keep the front suspension assembly 16 level with the center base 10. Note that the brake 70 may be disengaged to permit the front suspension assembly 16 to tilt clockwise or counterclockwise so that a free spinning tire can make contact with the ground or other solid object in order to achieve traction. However, it will be apparent to those skilled in the art that the tilt action may be controlled in a passive manner, or in any number of active manners such as using servo motors, hydraulic/pneumatic actuators, etc., as desired without departing from the scope of the invention.
FIGS. 5-6 illustrate a detailed cut-away view of the rear suspension assembly 42, in accordance with the disclosed embodiments. The rear suspension assembly 42 further includes a rear suspension mechanism 32, a rear differential base 92, a telescoping bar 100, and a Cardan shaft 84. The telescoping bar 100 is fixed to the rear differential base 92 and may slip in and out of the rear suspension mechanism 32, effectively elongating the rear suspension assembly 42 by a protrusion amount 78. It should be understood that the amount of protrusion 78 may be controlled by any means, for example, a servo motor, hydraulic/pneumatic actuator, manual crank, etc., such that it may vary from a minimum amount (fully dosed position) to a maximum amount (fully open position). FIGS. 5-6 illustrate the torsion springs 102 coupled with a worm gear/spur gear arrangement 108 to illustrate one possible means by which the rear suspension assembly 42 may be lowered, raised, and provided with a degree of adjustable suspension resistance.
FIG. 7 illustrates a side view of the front and rear suspension assemblies 42 and 16 aligned horizontally and a telescoping mechanism 22 fully open, in accordance with the disclosed embodiments. FIG. 8 illustrates a detailed cut-away view of the rear suspension assembly 42 with a minimum protrusion amount 78, in accordance with the disclosed embodiments. The telescoping mechanism 22 is in a fully closed position.
FIG. 9 illustrates a lateral view showing the rear suspension mechanism 32 rotated downward to create a positive ventral space for additional ground clearance, in accordance with the disclosed embodiments. The rear suspension mechanism 32 is rotated downward so as to create a positive ventral space for additional ground clearance, when needed. Even more ground clearance is achieved by extending the telescoping bar 100 to its full projection while in this position, as shown in FIG. 9. It should be understood that the rear suspension mechanism 32 may also be rotated upward if and when a negative ventral space is required as illustrated in FIG. 10. In addition, the front suspension assembly 16 may be raised or lowered independently or in conjunction with the rear suspension assembly 42 to achieve any number of configurations as required to overcome obstacles or navigate specific terrains, as shown in FIGS. 11-14.
FIGS. 15-16 illustrate a detailed view of the central multidirectional transmission system 50 that controls degree of tilt with respect to a longitudinal axis of the vehicle, in accordance with the disclosed embodiments. FIG. 17 illustrates an exploded view of the central multidirectional transmission system 50, in accordance with the disclosed embodiments.
FIG. 18 illustrates an exploded view of the rear suspension mechanism 32 and the torsion spring, worm, and gear arrangement, in accordance with the disclosed embodiments. A shaft 124 and a plate 148 are fixed parts of the rear suspension mechanism 32 which fits inside the hollow cylinder 82 (which is part of center base 10) and are free to rotate axially inside it. Gear 152 spins freely with respect to the shaft 124, but is engaged by the worm 108 which is mounted to the hollow cylinder 82. Torsion spring 102 also fits inside the hollow cylinder 82 and is attached to the plate 148 at one end and to the gear 152 at the other (with the shaft 124 running inside its coil axis). It should be understood that the worm 108 is meant to be turned via an electric motor, hand crank, or any other suitable means.
FIG. 19 illustrates an exploded view of the rear suspension mechanism 32 and the torsion spring, worm, and gear arrangement assembled inside a hollow cylinder portion 82 of the center base 10, in accordance with the disclosed embodiments. As the worm 108 is turned, it causes the gear 152 to turn around the shaft 124. As one end of the torsion spring 102 is held to the gear 152, turning the gear 152 causes the coils of spring 102 to tighten or unwrap, depending on the direction of turn. Such an approach causes the rear suspension mechanism 32 to rotate upward or downward (depending on whether the tension in spring 102 is being increased or decreased) and maintains a level of torsional resistance (which in effect would constitute a secondary suspension mechanism).
